From 2a94e19b00434fe4d7ab858a6cdcff6364f6e408 Mon Sep 17 00:00:00 2001 From: Alynx Zhou Date: Wed, 15 May 2024 00:07:41 +0800 Subject: [PATCH 2/2] wayland/text-input-v1: Implement basic text-input-v1 support This commit makes input methods work in text-input-v1 only clients (mostly Chromium/Electron based apps with Ozone Wayland), which is needed by users who needs IME to input their languages, like Chinese, Japanese or Korean.
